A value that is incremented or decremented and then not stored is at best wasted code and at worst a bug.
Noncompliant code example
int pickNumber() {
int i = 0;
int j = 0;
i = i++; // Noncompliant; i is still zero
return j++; // Noncompliant; 0 returned
}
Compliant solution
int pickNumber() {
int i = 0;
int j = 0;
i++;
return ++j;
}
